Reducing Lag Due to Location Based Services (Tested with myTouch)
Summary:
Only use GPS or Network Based Location services but don't have both enabled at the same time.
Background:
I purchased the myTouch on 08/20/09 running Firmware 1.5 (Cupcake), Build Number COC10. I am also using the 4GB card that came with the phone.
I found that Sherpa and Google maps tended be less than accurate and lagged significantly despite being in Downtown Seattle with 2 - 4 bars of service depending on building density.
I also had Pedometer running (a free app from the Market). Sherpa was exteremely laggy to the point of being useless in both Carsel Mode as well as Map Mode. I didn't use Satillite nor Street View in any of my testing.
Testing:
When I killed Pedometer, I found Sherpa seemed to improve a bit, but still, it was very clumsy to use due to lag. I then looked at "Security and Locations" services and saw both "Use wireless netowrks" and "GPS" enabled. I first disabled "Use wireless netowrks" and saw an immediate improvement in Sherpa. I reenabeld the Pedometer and still got a good response from Sherpa and Google Maps including reduced lag and more precise location. I then disabled GPS (and told the applications to cancel when asked to enable) and enabeld Network based services. Sherpa, Google Maps and Pedometer all responded well, location services improved in accuracy and little lag.
Conclusion:
Having both GPS and Network base location services in Cupcake seems to cause significant performance problems. Having only 1 of the two services enabled both improved performance and accuracy of location based services.
I hope this helps others.
